Abstract

Existing high-resolution experimental data collected with the MAGNEX spectrometer were analyzed to investigate peripheral collisions of medium-mass nuclei from the reaction ⁷⁰Zn (15 MeV/nucleon) + ⁶⁴Ni. The main focus of this work was to correlate the observed ejectiles with the excitation energy of their progenitors. Experimental excitation energy distributions were generated and compared with the Deep-Inelastic Transfer (DIT) model. This revealed a dominance of direct reaction mechanisms located at low excitation energies and more complex mechanisms at higher energies. Future efforts include further detailed studies of the excitation energy distributions to elucidate the multinucleon transfer mechanisms and to comprehend the resolution limits achievable with medium-mass nuclei such as ⁷⁰Zn.
